4citizen of the United States, have invented certain new and useful Improvementsjin Side Bearings withCoiitact-Shoes, off which the following is aY full, clear, andfeXa'ct description, such as will enable othersskilled i' in the art to which it appertains to make and to use the saine, reference being had to the accompanying drawings, which illustrate the preferred form ofthe invention,

tion is not limited to the exact detailsgof construction shown and described, Aasit is obvious that various modifications thereof' the underside of body bolster/1 is a casing within the scopev ofthe claims willV occur to persons skilled 'in the art.

In said drawings Figure l is a viewv of my improved side bearing partially in plan, and partiallyin horizontal section to show the relation of some of the internal members;

Fig. 2A is a transverse section taken lon the line 2-1-2 of Fig. l; and

Fig. 3 is,` a longitudinal vertical section i taken on the line 3--3 of Fig. l.

This invention relates to antifriction Y bearings applicable to the holsters of rail- 30 casing or housing is provided, `which Yis adapted, to be attached to a bolster yat a proper location, such casing being provided with separate runways, there being rollers adapted to bear on andtraverse either runway.

t is a purpose to yinterconnectr a shoe,

adapted to bel engaged and actuated by another and V`:cooperating bolster, with the --withstand it.

ywill cause the rollers `,tobe'supportedbv it and; 'further .causedl to roll onjy the runway opposed tothat on'V which lthe'rollers normally bear. YThe shoes, rollers and last mentioned runway are then to contact with each other and be in compression, the parts under u n n y n n .l y

trackr` formedby flanges 7, shoe 13 -will be this stress being adequately rugged'to-easily V The shoe and riinw ys'farein anti-frictional engagement withithe ro1lers,'irrespec hereinafter, of course, f of the present invention.

1- tive Vof which runway the rollers travel'on, and a further'feature lies in the ability 0f the shoe to provide a bearing at points be- 'l yond thebolster.V Theshoe may thus-eX- tendv itsefective engagements'with the bol-t fster actuating itv beyond the possible travel f ofthe rollers, and beyond the extent of such side bearings as have selffcontained rollers.

iOther featuresy manifesting themselves n Referring to the drawing, indicates a body bolster of'a railway car and 2 the bearing carried thereby, both being indicated'fby dotV and ldash lines. Positioned on orflio'using 3 comprising` 'sidewalls Land "an`overhead wall 5. Projecting from vthe upper portions of side walls et, are lugs kor flangesv 6 throughl which fas'teningineans are adapted to pass to secure vthe casing 3 1 to the body bolster 1. l.Projectinggg' inwardly from each sidewall `aoffcasing 3 isa vbot-- tom flange 7,5 said flanges constituting ay lower' track,"` The `.terminals of anges "Z are come within the scope upti`iri`1`e`d,` yas indicate'datflO in dotted lines in Fig. 3, yto'forin stops, hereinafter referred to. -Positioned` above and `rextending over i wa)T Cars to act as side bearings.

I general offcliaiinel-sliaped forinhavingboth V v Whenever the car body tilts, as in responseto of its endslopen-fand after the -insertionof rollers l1 and shoe 1.8, said rollers 11 will normally rest upon the trackflariges 7.

Thereafter, Wearing strips 8 inay be inserted' andsecured as previouslyindicated, Whereupon the terminals ofivearing-strips Savill jrounding a curve, body bolster 11and'ztruck bolster 2 will relatively approacheacli other ,on Oneside ofthecar. When this happens,

truck bolster 2, or the siderbearing'inounted thereon, Will engage the under side of shoe 13 forcing it upwardly between laterally eX- Atndingrg spaced Wearing strips 8, butinotfsui'liciently for .it to encounter the overhead Wall 45. j 1 Y In moving upwardly, thelower. or` engagement portion ofshoe .13 will encounter the rollers 411 raising tlieinr so asto cause them to bear `upon ,thel under sidesof Wearingstrips 8,.along` Which theyv are .then adapted to .be rolled by `.the shoe liinderthe influencent truck bolsterl 2. l

LUnder this condition', theflower thick por- 4tionof shoe13 the solid rollers 11, .which may be tubular ifdesired, and the Wearing strips 8 are in a .state ofcoinpression.

Duringthe continued relative svviveling of the bodyand truck bolsters,-and at such time as the-truck-bolster has actuated the shoe-lwtoraiserollers 11 into contact'with `Wearing strips 8, the rollers andshoel Will move transversely of body bolster 1. There Will be a 'relative Aopposite rollingxof the under surfaces of Wearinglstrips 8 Aand the shoe y13 onthe rollers llzivhen said rollers and shoe are traveling as :1iiidicated, fand a fter-a certain aniountfof: travel inf-one direcminalstopsflO at one end offlanges 7. The roller so arrestedfwill 'also beA engagedby;r the vinner #Wall `of ,loop 14, `which engagement causes the shoe to ibe lheld in fixed relation to vvthe casing -linfaj position` in which the-shoe protrudes fromithe endof .the casing, thereby foriniiigfa further-track forthetruck bearing.l to engage asthe truck conti-nuesto 'j swivel: -This action is adapted tol4 takefplace their normalgpositions, asvindicated inTig.

the rollers again become lridable on the vlower track formed b y flanges 7, and, due to the anticlinal upper portions of the loops '14,

the shoel' ivill automaticallycenter itself lon the rollers `11 by gravity.

`The `side bearing is then ready for a repetition of the just described actions, responding `rtothe influence of truck bolster 2 in Which- Y,andeconomical-toproduce and constitutes a highlyeliicient side bearing quite unlikely If at any time rthe rollers-.should accidentally become jammed 'between the sidefwallsrlfof casing 3,tliis will not result. in thev inoperativeness of the device as shoe lqvill reciprocatefas before.
